Event overview
The Windsor Half Marathon takes place on 27 September 2026 in Windsor Great Park. The event is a Half Marathon run on a two-lap course. The course has been measured by UK Athletics using the shortest possible route (SPR), so a runner's GPS device may show a slightly different distance. Roads inside Windsor Great Park will be closed for a limited period on race day. Water stations and medal collection are provided during the event.
Entry, eligibility and rules
Early bird entry fees listed include £33.50 for UK entries and £36.00 for overseas entries. Entries close on 31 January 2026 and transfers are allowed through the registration system until 31 August 2026. Entrants must be amateur and at least 17 years old on the race date. The race is held under UK Athletics rules. Entry fees are non-refundable; a one-year deferral is available for entrants unable to participate due to pregnancy. Runners must wear their race number visibly on the front and complete personal and health details on the back of the number. No wheeled vehicles, dogs or following cycles are permitted. Personal stereos and audio devices are allowed with caution; in-ear headphones are strongly discouraged. Race marshals and medical staff may remove or disqualify competitors for safety reasons.
